Description
The present invention is directed to efficient storage of a spare
tire for a motor vehicle on the exterior portions thereof. The
invention provides a spare tire mount assembly which permits the
user thereof to store his spare tire at either one of two positions
on the vehicle thereby permitting ready access to the rear of the
vehicle or to permit long objects to be carried in the vehicle that
would project beyond the position normally occupied by the spare
tire. The pivotal mounting also can be used merely to move the
spare tire temporarily out of the way of the rear tailgate.
Although the quality of tires has markedly improved, it is still
considered necessary that an automobile or truck be provided with a
spare tire in the event that a flat occurs. While my invention will
undoubtedly find use in several types of vehicles, it will be
described with particularity on a vehicle of the station wagon
type. In such vehicles it has been proposed in the past that an
external mounting for the spare tire be used to save space on the
inside of the vehicle for carrying of other objects including
passengers. The most common recent location of such spare tire
mounts has been upon the rear of the vehicle generally centered
thereon for symmetrical appearance. However, in such a position the
spare tire and mount interferes with ready access either to the
trunk portion of a passenger vehicle or it interferes with the
operation of the tailgate and rear window assembly of a station
wagon. Through the use of my invention the spare tire may be
mounted in this normally desirable position at the immediate center
rear of the vehicle and yet can be readily stored without
substantial effort from the operator in a second position along the
side of the vehicle, thus providing ready access to the rear of the
station wagon. This two-position capability of my invention is
provided by having the spare tire assembly pivotally mounted to one
end of an elongated supporting arm member which is mounted at the
opposite extremity thereof by pivoting means to the body of the
vehicle. Thus, without removal of the spare tire from the assembly
the spare tire can be pivotally repositioned to either one of two
positions, or, if desired, may merely be moved out of the way
temporarily for purposes such as loading and unloading the rear
portion of the station wagon.

position for storage as in FIG. 3.
It should be understood that in each of the several figures and
descriptive matter that follows like parts will be given the same
numerical designation.
Referring first to FIG. 1, there is shown in rear elevational view
a station wagon-like vehicle generally designated 10 of the type
commonly sold for use by the general public as a combination
pleasure and utility vehicle. Such a vehicle typically is provided
with a rear bumper assembly 11. It also is provided with a rear
window panel 13 which is pivotally supported by hinges 12 which
permit a pivotal raising of the rear window. A tailgate assembly is
provided by hinges 14 which permit the rear lower panel 15 to move
down into a horizontal position to form an extended tailgate.
Centrally mounted at the rear portion of the vehicle is a spare
tire 16 which is mounted upon a central wheel rim 17.
The spare tire and rim arrangement is in turn supported by an
elongated arm 18 that is pivotally mounted at one end thereof by a
pivot 19 to a bracket assembly generally designated 20 which is
shown affixed to bumper 11. Of course, bracket assembly 20 can also
be mounted to the chassis of the vehicle instead of being bumper
mounted although bumper mounting will not require any significant
modification of existing vehicles. At the opposite end of the arm
18 a spare tire mounting arm 21 is provided for attaching wheel rim
17 thereto. Only the lower portion of this assembly 21 is visible
in FIG. 1.
Also illustrated in FIG. 1 by dotted outline is the alternate
position for storage of the spare tire assembly. As can be seen arm
18 has been rotated about pivot 19 and tire 16 has been rotated
upon arm 21 so that it is positioned as shown along the side of the
vehicle and parallel to the length of the vehicle.
Referring to FIG. 2, there is a side elevational view of the spare
tire mounting assembly after it has been rotated about pivot 19 so
as to position the spare tire parallel to the side of the vehicle.
In this position the spare tire no longer interferes with operation
of tailgate 15. Tailgate 15 may now be opened or even left in a
downward position as if spare tire 16 were not externally
stored.
In FIG. 3 is shown an alternate form of the invention wherein the
tire assembly as illustrated in FIG. 2 has been provided with a
pivot to provide a partial clockwise rotation of spare tire 16
about the longitudinal access of arm 18 thereby storing the tire
further along the vehicle with less overhang of the tire beyond the
rear end of the vehicle.
Turning now to FIG. 4 there is illustrated in cross-sectional view
and in detail apparatus in accordance with the invention for
performing the various storage positions illustrated in FIGS. 1, 2
and 3. In the Figure a bumper 11 has had attached thereto an upper
clamp element 22 and a lower clamp element 23 which are joined to
one another by means of a large bolt 24 which extends through
suitable holes in clamp elements 22 and 23. Clamp element 23 is
joined to bumper 11 by means of a bolt 25 extending through the
clamp element 23 and through bumper 11.
An elongated arm member 18 is mounted pivotally at one end thereof
between clamp elements 22 and 23 by means of bolt 24 which passes
through a hole in the end of arm 18 and is locked by connecting nut
26. Arm 18 is thus permitted to rotate in a plane perpendicularly
to the plane of the paper about bolt 24.
Arm 18 is preferably formed of a tubular member having a circular
cross-section throughout most of its length with the portion at the
end pierced by bolt 24 being of a rectangular cross-section. At the
opposite end of arm 18 to bolt assembly 24 there is provided a
welded collar member 27 having an opening 28 passing through the
center thereof and having indexing openings 29 around a radius
thereof. Cooperatively engaging 27 is a second collar-like member
30 having an elongated shaft 31 welded to the axis and extending
through opening 28 of collar 27. Member 30 also has mounted to and
projecting from a surface thereof pin members 32 diametrically
opposed along the axis of member 30 and positioned to cooperatively
engage diametrically opposed holes 29 of element 27. Thus, when
element 27 and element 30 are in juxtaposition pins 32 will be
inserted in one of the sets of holes in member 27 locking shaft 31
and member 30 from rotation.
As can be best seen in FIG. 4, shaft 31 extends along the length of
tube 18 and passes through a pair of aligning washer members 33
which are fixed in position relative to tube 18 by welding or the
like. The function of washers 33 and of the opening 28 and collar
27 is to permit member 31 to slidably move along the length of rod
18 and yet be relatively free from transverse motion. By means of a
spring 34 attached to the end of rod 31, rod 31 and its supporting
member 30 and biased toward the bumper assembly, although spring 34
can be overcome by pulling away from the bumper assembly thereby
permitting rod 31 and its attendant connecting member 30 to rotate
about an axis perpendicular to that of the longitudinal direction
of tube 18. The extent of travel of rod 31 is limited by spring 34
and can be further limited by suitable stop means such as by
threading the spring end of rod 18 and use of a nut thereon. The
opposite end of spring 34 can be suitably mounted to tube 18 by
means of a pin 35.
Fixedly mounted to the outer side of collar 30 as by welding is an
extension of tube member 18 which is designated 36. Extending
vertically upwardly from member 36 is a spare tire mounting bracket
37 which is mounted by means of bolts 42 to the tire rim 17. Member
37 has an L-shaped flange 38 which has a pin 39 passing
therethrough and into tube 36. This pin permits rotational movement
of member 37 about pin 39 so as to change the axis of the tire
mount 37 through a 90.degree. motion. Means such as pin 40 are
provided for locking member 37 at either end of its 90.degree.
rotation. Member 40 can desirably be constructed of a pin member
having an extension 41 for aid in manipulating the pin in a
vertical motion. A spring means (not shown) can be utilized to bias
pin 40 downwardly into member 36. Suitable holes are provided in
member 36 for latching assembly 37 by means of pin 40 in each of
the two positions.
Also illustrated in FIG. 4 is a latch pin member 43 having a lower
portion 47 at a right angle thereto passing through an opening in a
guide member 46. Latch pin 43 is positioned within an elongated
slot 44 having its longitudinal axis extending along the length of
member 36. A spring 45 biases latch pin 43 toward the bumper
assembly. The purpose of latch pin 43 will be best understood in
reference to FIG. 6.
In FIG. 6 there is illustrated the bumper mounting assembly as
illustrated in FIG. 4 and further illustrates two arm support and
lock arrangements generally designated 48 and 49 respectively. Arm
aupport and lock 48 and 49 are similar in construction with the
exception of an engaging slot member. Member 48 consists of a
bracket having a U-shaped cross-section that is mounted by means of
a bolt 50 and a curved upper portion 51 to the bumper assembly. The
lower portion of the member 48 consists of a flat plane 52 having
the forward edge thereof generally tipping in a downwardly
direction as shown. This lower edge 52 is designed to act as a rest
and support for arm 36 when arm 18 is pivoted about pin 24 into the
position shown in FIG. 1 with the tire in the center of the rear of
the vehicle. As a means of maintaining the arm in supportive
relationship to bracket 48 there is an upper outwardly projecting
flange 53 having a slot 54 of a configuration as shown. The entire
assembly 48 is positioned so that the slot 54 is able to receive
latch pin 43 when arm 18 is pivoted so as to engage member 36 with
surface 52. The initial angle of slot 54 forces latch pin 43 out
against spring 45 until arm 36 is tightly pressed up against
assembly 48. Latch pin 43 is then free under the bias provided by
spring 47 to slip into the rear portion of slot 54. In this
position the entire assembly cannot pivot about pin 24 as it is
restrained by the lip portion 55. To release the arm from this
position the operator merely presses against latch pin 43 so as to
move it against the bias of spring 47 out into a region where the
arm can be pivoted free from this latch.
Member 49 functions as element 48 with the exception that slot 56
has been shaped so as to provide the latching arrangement as does
slot 54. The two slots are essentially mirror images of one
another.
Other means can be provided for fixedly positioning arm 18 at each
end of its pivotal motion. For example, a simple pin and hole
arrangement at the region of pivot pin 24 can be used. Holes
through member 24 and arm 18 in alignment at the extreme ends of
rotation can be used in conjunction with a pin to fixedly position
arm 18.
The operation of the invention should now be apparent. If the tire
is in its normal riding position as shown in the solid outline of
FIG. 1 and the operator of the vehicle desires to move the tire out
of its stored position, he merely presses against latch pin 43 so
as to allow latch pin 43 to be disengaged from slot 54. By pulling
outwardly arm 18 pivots about pin 24 to move the tire away from the
rear of the vehicle. The tailgate can now be opened if desired. If
it is desired to leave the tailgate down or readily accessible the
operator proceeds as follows. Once the tire is removed away from
the rear of the vehicle the operator can then raise pin 40 by means
of extension 41 to permit the spare tire to be rotated about a
90.degree. turn. Then arm 18 can be continued in its rotation until
it has traversed 180.degree. and the tire is in position along side
the vehicle as shown in dotted outline in FIG. 1 and as illustrated
in FIG. 2. At this position latch pin 43 is engaged by assembly 49.
To store the tire in the forwardly tilted position of FIG. 3, the
operator merely pulls outwardly upon assembly 37 so as to disengage
pins 32 of plate 30 from openings 29 of plate 27. Then the entire
end assembly 36 can be rotated along with rod 31 to the second
position of the tilt shown in FIG. 3. The operator then merely
releases his outward pressure on assembly 37 allowing pins 32 to
engage with the second set of openings 29 and plate 27 is thus
prevented from further rotation. Of course, bracket 49 can be used
to support the outer end of the arm assembly 36 either before or
after rotation of the tire and bracket 37 to the position shown in
FIG. 3.
Turning now to FIG. 7 there is illustrated in cross-sectional view
and in detail a modified form of the invention which possesses
certain advantages of simpler construction over the form previously
described. In the Figure parts which are substantially identical to
those of the earlier Figures have been given the same numerical
designation. An elongated arm 18' which is preferably formed of a
rectangular cross-section hollow tube is pivotally mounted by means
of holes therethrough and pin 24 to the bumper bracket assembly as
in the case of the description of FIG. 4. At the opposite end of
arm 18' is a plate member 57 which has been attached as by welding
to arm 18'. Above plate 57 is a substantially matching plate 58
which is held in pivotal engagement to plate 58 by pin 59. Thus
plate 58 may pivot about an axis perpendicular to that of arm 18'.
Suitable holes and a pin 60 is provided for locking plates 57 and
58 in relative rotational position to one another as desired.
Extending upwardly from and connected to plate 58 is a vertical
post member 61 which is shaped in the manner best seen in FIGS. 8
and 9. A tubular member generally identified 62 has had the lower
central portion thereof removed to produce a fork. Assembly 62 is
pivotally joined by pin 63 extending through the tines of the fork
portion thereof and through vertical post 61. An adapter 64 with
suitable holes for bolting on a spare tire is mounted to element
62.
Arm 18' is provided with a latch pin 43 and assembly which are
substantially the same as that described with respect to FIG.
4.
Turning to FIG. 8 there is illustrated in partially cross-sectional
view the assembly of FIG. 8 viewed from the right side of the
Figure. In this Figure the spare tire and its mount 64 are not
shown in detail for sake of clarity. It can be seen that upright
post member 61 has a stop member 65 which has been attached to
member 61 as by welding. This stop member can be a simple block of
metal which extends outwardly from one or both sides of member 61
so as to block pivotal motion of the fork in the counterclockwise
direction from the position shown. Post member 61 also has an
extension to the right-hand side thereof identified 66 whose
function will be explained. At the lower portion of extension 66 is
a second stop member 67 which acts to prevent rotation of the fork
in a clockwise direction in a manner analogous to stop 65. As can
be seen from the Figure the upper portion of post 61 has been
provided with a V-shaped trough 68 whose function will now be
described.
Upper member 62 is mounted via pin 63 to post member 61 for pivotal
movement thereabouts. The forked portion of member 62 is indicated
by dotted outline 69.
Desirably member 62 is formed of a square or rectangularly shaped
tube member. Slidably positioned within the interior of member 62
is a wedge 70 having a forward portion 71 which is shaped to
conform to V-shaped trough 68. Wedge 70 is mounted to a threaded
rod 72 which passes through a threaded hole in plate 73. That is
fixed relative to tubing 62 by appropriate means such as welding.
At the upper end of rod 72 there is provided a knurled handle 74
which can be used to advance or retract wedge 70 to and from its
locking engagement with V-shaped groove 68.
It should now be apparent that member 62 is not free to pivot in
relation to post 61 as long as wedge member 70 is pressed into
engagement with V-shaped notch 68. However, when wedge 70 is raised
above groove 68 the assembly including the spare tire can pivot in
a clockwise direction about pivot 63. It is restrained from
pivoting in a counterclockwise direction, as already noted, by stop
member 65.
Turning to FIG. 9 the assembly is shown with member 62 pivoted
about pin 63 to a second stop position determined by stop 67. Wedge
70 has been once again advanced to lock into engagement with the
shoulder 68 attached to post 61 thereby locking the assmbly in the
position shown. In this position shown in FIG. 9 the spare tire is
in appropriate position for storage along the side of the vehicle
as illustrated in FIG. 3.
The operation of the assembly in accordance with FIGS. 7, 8 and 9
should now be apparent. One can pivot arm 18' so that it can be in
the position shown by the solid outline of FIG. 1 or in the dotted
outline of FIG. 1. The entire mounting assembly for the spare tire
including the vertical post member can be rotated in either a
clockwise or a counterclockwise direction about an axis vertical to
that of arm 18'. Once the desired position is achieved the plate
member 58 is locked in relationship to plate 57 by means of pin 60
passing through holes in each of these plates. By backing off wedge
70 from V-shaped trough 68 or 68' the upper portion of the spare
tire mounting assembly 62 can be pivoted to either the position
illustrated in FIG. 2 or in FIG. 3.
Various modifications of my invention will now be readily apparent.
When desired, suitable electric harnessing arrangements can be
utilized to provide a light in the midst of the spare tire mounting
assembly. This will be advantageous when the spare tire is in
position along the side of the vehicle as shown in FIG. 2 to
provide taillight illumination of the side of the vehicle.
Likewise, any of a variety of prior art locking arrangements can be
used to prevent theft of the externally positioned spare tire.
